Just wondering if anyone has any experience with the following issue/observation…
Currently have a ISR4331 (SIP) to CUCM 11. On the 4331, I have a BRI which works all ok in/out, however, I am only getting “MULTIPLE_FRAME_ESTABLISHED” when there is a call in progress;
ISDN BRI1/0/0:0 interface
dsl 0, interface ISDN Switchtype = basic-net3
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 89, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Layer 3 Status:
0 Active Layer 3 Call(s)
CCB:callid=17, sapi=0, ces=1, B-chan=1, calltype=VOICE
Active dsl 0 CCBs = 1
The Free Channel Mask: 0x80000002
When the call ends, after approx. 10 seconds or so, the ISDN returns to deactived state;
ISDN BRI1/0/0:0 interface
dsl 0, interface ISDN Switchtype = basic-net3
Layer 1 Status:
DEACTIVATED
Layer 2 Status:
Layer 2 NOT Activated
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 0 CCBs = 0
The Free Channel Mask: 0x80000003
As I mentioned – not causing an issue for calls however when we are monitoring and from an alert perspective, getting spammed for UP & DOWN alerts.
Current config;
interface BRI1/0/0:0

Anything I can do to keep this established as it would normally do in MGCP?
